Subject RE: video compression

Hi Mallik,

This is a good wish list, but there are challenges around running compressions across a hadoop
cluster. Not all compression algorithms are suited for running through map-reduce, since most
of the compression algorithms are very much context driven and tree based, so its hard to
break them across various map-reduce tasks. LZO compression is however a parallel compression
algorithm and has can be run in a map-reduce paradigm. The video compression however are different,
and whether they can be achieved via map-reduce is something that will depend on, as to how
much parallel compression the specific video compression algorithm supports.

Thanks and Regards
Pankaj Misra
